REGIONAL OVERVIEW
Climate variability and change pose major
obstacles to resilience in East Africa, where
increasing temperatures and shifting rainfall
patterns are already affecting economic growth,
livelihoods, food security, health, and
ecosystems. The population of 421 million in
the 10 countries covered in this profile stretch
across 7.8 million km2 of land — about a
quarter of the African continent. The region is
characterized by rapid urbanization at 4.0–6.2
percent annually for much of the region, higher
than sub-Saharan Africa as a whole, which is
one of the world’s most rapidly urbanizing areas.
More than 70 percent of the population,
however, still live in rural areas where
population growth continues and people rely
heavily on climate-sensitive rainfed agriculture.
Projections indicate that reduced crop
productivity in much of the region is expected to
increase poverty and food insecurity among populations where current poverty rates range from 21 percent
(i.e., Djibouti, Uganda) to 64 percent (i.e., Burundi, Democratic Republic of the Congo [DRC]).

CLIMATE RISK PROFILE: EAST AFRICA | 2
This combination of urbanization and declining agricultural productivity will affect livelihoods, health,
infrastructure, and food security. In the Lake Victoria Basin, home to approximately 45 million people across
areas of Burundi, Kenya, Rwanda, Tanzania, and Uganda, drought in recent years has already pushed more
than 10 percent of the population toward chronic food insecurity. Climate-sensitive diseases like malaria are
poised to expand into the warming East African highlands and Lake Victoria region. Within sub-Saharan
Africa, the region is expected to see the most marked increase in areas of malaria suitability; by 2030,
approximately 10–15 million additional people will be at risk in historically malaria-free areas. In Tanzania, for
example, new cases are emerging in Tanga, Kilimanjaro, and the Arusha highlands; in the DRC, analysis
suggests that by 2030 an additional 65,000–80,000 people will be at risk from endemic malaria in areas
previously unsuitable for malaria transmission. (6, 7, 40, 41, 73, 72, 76, 74, 80)
Increasing temperatures and more frequent and intense extreme weather events are expected to lead to
land degradation and infrastructure damage and destruction, with consequences for human health. In urban
and periurban areas, increased flooding is already straining limited drainage and sanitation infrastructure,
with implications for infrastructure integrity and water quality. In Rwanda, heavy rains in 2012 leading to
extensive flooding caused an estimated loss of 1.4 percent of gross domestic product (GDP). Sea level rise
and coastal erosion along the region’s 3,000 km of coastline (i.e., Djibouti, Kenya, Sudan, and Tanzania)
threaten coastal urban areas, ports, aquifers, agriculture, and ecosystems. In Tanzania alone, sea level rise
is expected to cost about US$200 million per year by 2050 in lost land and flood damage. (6, 7, 40, 41, 73,
72, 76, 74, 80)
CLIMATE SUMMARY
East Africa’s climate zones are diverse, ranging from arid to temperate to tropical (see map on p. 1). The
varied geography spans coastal regions, deserts and savannas, vast forests, lakes including Lake Victoria,
the second largest freshwater lake in the world, and mountainous areas including Africa’s two tallest
mountains, Mt. Kilimanjaro and Mt. Kenya. Temperatures are high and characterized by little seasonal
variation across much of the region. Temperatures are lower in the highland regions of Ethiopia, Kenya, and
Tanzania. Annual average temperatures range from as low as 6°C in high-elevation areas of Kenya and
Tanzania to around 26°C in coastal areas and up to 30°C in the northern interior (i.e., Sudan). There are
three main rainfall regimes—in equatorial regions (much of the area described), there are two rainy seasons
with peaks in October and April; in the north, the primary rainy season is June to August; and in the south the
primary rainy season is December to February. These seasons are linked to the annual north–south
movement of the precipitation-inducing Intertropical Convergence Zone, which shifts toward warmer air
bringing rainy seasons in the respective warm months of areas north and south of the equator. Additionally,
precipitation is periodically influenced (every two to seven years) by the El Niño Southern Oscillation, leading
to alternate periods of above- and below-average rainfall. Annual rainfall averages from nearly 0 mm in parts
of northwest Kenya to over 2,000 mm in highland areas and in the DRC. There is substantial interannual and
interdecadal rainfall variability, and both droughts and floods are common. (14, 34, 45, 52)
CLIMATE TRENDS AND PROJECTIONS There has been a clear trend of increasing average temperatures across East Africa since the 1960s, while
precipitation trends have been weak and variable. Climate models indicate continued increases in average
temperatures (and heat waves), as well as the frequency and intensity of heavy rainfall events. The future of
overall precipitation changes is less certain, with the majority of models showing increased precipitation for
much of the region (with the exception of southern Tanzania) but with shifts in seasonality. The table below
outlines these shifts throughout the region. Despite potential precipitation increases shown in some models,
droughts are expected to intensify in the 21st century due to longer dry spells combined with increased
evaporation and a greater proportion of precipitation coming in heavy rainfall events. (6, 14,15, 20, 21, 22, 23,
24, 25, 35, 52, 71)

SECTOR IMPACTS AND VULNERABILITIES
CROP PRODUCTION Warming temperatures and changing
precipitation patterns are expected to
decrease subsistence and cash crop
production, which remain a critical source
of livelihoods and economic activity across
the region. Aside from Djibouti, DRC, and
South Sudan, agriculture exceeds 24
percent of GDP in all countries. Small-
scale farms account for up to 90 percent of
crop production across the region and the
main source of employment for the region’s
297 million rural residents. The dominant
crops are a cereal–legume mix that
includes maize, millet, sorghum, wheat,
and beans; major cash crops include
coffee and tea. Already low yields resulting
from low-input rainfed production with
limited processing, storage, and
transportation infrastructure make the vast
majority of crop production highly vulnerable to changes in temperature and rainfall. Heat and water stress
are expected to reduce maize, bean, banana, and plantain yields at lower elevations by the 2030s to 2050s.
However, in higher elevations, temperature increases are projected to expand the areas for crop production
potential. This expanded production potential could increase to cultivation pressure on mountain slopes and
in protected areas with implications for ecosystem services and biodiversity. Maize, which accounts for
nearly half of calories consumed in the region, is expected to experience yield reductions of 8–37 percent
across East Africa by the 2090s. Lowland bean production, vital for nutritional security, is expected to
become unviable due to rising temperatures sometime after midcentury, particularly affecting Tanzania and
Uganda. In drier areas of East Africa (especially South Sudan and Sudan), even drought-resilient millet,
sorghum, and cassava yields may become increasingly marginal. Wetter rainy seasons could prevent staple
crops (e.g., maize, sweet potatoes) from maturing, although increased rainfall would be favorable for other
crops (e.g., perennials and a range of fruits and vegetables). A warmer, wetter climate may also raise crop
and postharvest losses due to heightened risk of mildew, leaf spot, and bacterial stem and root rot and
increased fungus growth in stored seeds. (1, 8, 36, 51, 52, 63, 67, 80)

CLIMATE RISK PROFILE: EAST AFRICA | 4
Increasing heat and pest stress (e.g., coffee berry borer) are expected to diminish the area suitable for coffee
and tea production by 20 to 40 percent across Burundi, Ethiopia, Kenya, Rwanda, and Uganda by 2100.
However, the areas suitable for coffee production are expected to expand into higher elevations as well,
which has negative environmental implications (e.g., deforestation, reduced water availability, nutrient
loading in streams). For East Africa’s water-intensive cut flower industry, heat and water stress, heavy
rainfall resulting in soil degradation, and growing tensions over access to limited water resources threaten
production. Along the coast, sea level rise is expected to increase water logging, salinization, and inundation
of agricultural lands with particular risk for mango, cashew, and coconut harvests. (1, 11, 32, 52, 55)
LIVESTOCK
Rising temperatures, shifting rainfall patterns,
drought, and increased heavy rainfall events are the
most significant stressors facing the region’s main
livestock species: cattle, sheep, goats, camels, and
poultry. East Africa’s livestock are integral for the
region’s culture, as well as food security and
livelihoods, particularly in arid and semi-arid lands,
and contribute significantly to annual GDP, including
approximately 20 percent and 25 percent in Ethiopia
and Kenya, respectively. Livestock provide critical
sources of meat and milk production, income,
investment, credit, and savings. As climate variability
and change, including heat and water stress, make
crop production more tenuous, livestock production
is expected to replace areas of mixed crop–livestock
systems in some coastal and mid-elevation areas by
the 2050s. While typically more resilient to climate
variability and shocks than crops, livestock are
susceptible to heat stress, and their viability is
affected by the productivity and availability of pasture, feed production, water availability, and pest and
disease dynamics. Recurrent climate-related shocks are already leading to critical livestock losses. During
Kenya’s 2008–2011 droughts, the country’s economy lost an estimated US$12.1 billion, with livestock losses
accounting for more than two-thirds of the total. Heavy rains across the region from March to May 2018 led
to extensive flooding and livestock deaths, including the loss of 20,000 livestock in Kenya and 700 in
Rwanda. (30, 41, 52, 57, 58, 59, 60, 61, 70, 73, 77)
Livestock are also susceptible to heat stress that reduces feed intake, reproduction rates, milk production,
and longevity. Rising temperatures and flooding could also increase the incidence of diseases, such as
anthrax and Rift Valley Fever, and expand the range of ticks carrying diseases such as East Coast Fever.
Increased seasonal and drought-related water stress, alongside warming trends, have already impacted
pastures, fodder crops, and water availability in some areas, including the Lake Victoria Basin. For
pastoralist communities, climate-related changes in pasture and water availability could alter pastoral
mobility, exacerbating tensions over land and water resources in the region. Drought years in Ethiopia’s
Borana Zone, for example, are linked to an increase in violent conflict over grazing areas, water points, cattle
theft, and boundary disputes. (37, 40, 41, 52, 67, 72, 75)

WATER RESOURCES
Increasingly severe flooding and drought, in addition to rising evaporation rates and shifting rainfall patterns,
will diminish East Africa’s water quality and reduce water availability. For example, this could occur when
rapid runoff from heavy rainfall, rising evaporation rates, and drought offset increases in rainfall. While
access to water and sanitation in East Africa continues to improve, unsafe drinking water and inadequate
sanitation remain critical health concerns, particularly in rural and rapidly growing periurban areas. Projected
increases in flood and drought occurrence exacerbate these challenges and threaten progress toward sector
development goals. Low access to basic sanitation—less than 50 percent of the population across all 10
countries and just 20 percent in rural areas— increases the risk of water contamination during heavy rainfall
events. Population growth combined with heavy rainfall events is increasingly contaminating the Lake
Victoria Basin with waste from neighboring countries. Research also suggests that more frequent heavy
rainfall events and warming water temperatures will lead to a greater incidence of waterborne disease
outbreaks (e.g., typhoid, cholera, schistosomiasis, and diarrhea). The risk factor is exacerbated by the fact
that less than half of the region’s urban population has access to clean and safe water supplies. Diarrheal
diseases are already a leading cause of mortality in children and adults, with surges in cases linked to
flooding. The expected increase in consecutive dry days may also lead to longer water storage times, further
increasing the risk of contamination and pathogen growth during storage. (15, 38, 52, 53, 56, 68)
Higher temperatures that increase evaporation,
shifting rainfall patterns, and longer dry spells
will also impact the region’s numerous
transboundary water resources. Arid and semi-
arid lands, particularly in the north of the
region, already experience high levels of
baseline water stress where water withdrawals
approach the total amount of fresh water
available. Evaporation and precipitation trends
combined with irrigation and hydropower
development are expected to reduce river
flows and exacerbate water stress in the
socioeconomic and geopolitically important
Nile River Basin. Research estimates that Nile
Basin flows may increase through the 2030s
but decline after the 2050s. In contrast,
increasing rainfall is expected to balance or
outweigh rising evaporation rates, resulting in
a negligible change in total runoff in the Congo
basin and increased runoff in the Lake Victoria
Basin, including for the Mara and Nyando
rivers. In coastal aquifers, reduced freshwater
flows during longer dry spells may increase the
risk of saline intrusion, which will be further
exacerbated by sea level rise. (32, 33, 41, 52, 81)

HUMAN HEALTH
Rising temperatures and shifting rainfall
patterns are likely to impact numerous health
outcomes. Climate change and variability
increases both direct health risks (e.g., the risk
of respiratory diseases and dehydration due to
more intense heat waves) and indirect risks
(e.g., changing the incidence of infectious
diseases). A warmer climate is expected to
increase the incidence of vector- and
waterborne diseases, including malaria,
dengue, and cholera, with 45–65 million more
people at risk from malaria in East Africa by
the 2050s. Some areas 2000 m above sea
level, historically unsuitable for malaria, are
expected to shift toward endemic (year-round)
suitability as early as 2030. Dengue is expected to increase in much of the region, particular in the DRC and
neighboring countries, but potentially decrease in some areas that exceed temperature and dryness
thresholds (e.g., areas of eastern Ethiopia and Sudan). Rising temperatures and longer heat waves are
linked to increased mortality rates and the worsening of cardiovascular and respiratory diseases. (42, 46,
52,70, 76)
Heat stress will particularly affect the elderly, children, and those in warmer lowland and dense urban areas
(a number increasing with urbanization), such as informal settlements in Mombasa, Kenya, Dar-es-Salaam,
Tanzania and Kampala, Uganda, where temperatures can rise dramatically due to the urban heat island
effect. In Ethiopia, heat-related mortality among the elderly is projected to increase from 3 deaths per
100,000 people annually in 1990 to 65 per 100,000 annually by 2080. Outside of the region’s highlands, the
number of days with deadly heat annually is expected to increase from nearly zero in 2000 to between 50
and 350 by 2100. Increased flooding poses an additional risk to human health. In 2018, flooding across the
region led to extensive loss of life, more extensive cholera outbreaks (e.g., DRC and Kenya) and critical crop
and livestock losses. (2, 17, 44, 48, 49, 56, 57, 58, 59, 60, 61, 62, 66, 78, 79, 80)
The impacts of warming temperatures, shifting rainfall patterns, and sea level rise on agriculture are
expected to exacerbate food insecurity and malnutrition in this region, where high rates of undernutrition and
stunting in children under five persist (i.e., 43 percent and 56 percent in DRC and Burundi respectively).
Across the drought-sensitive countries in the region, the number of undernourished people increased from
113 million in 2005 to 133 million in 2018. Additionally, from the mid-1990s onwards, higher incidences of
child malnutrition have been correlated with periods of drought in the Horn of Africa (e.g., 2003, 2010); higher
food prices that often occur as a result of drought-induced food shortages have also been associated with
the prevalence of underweight children. Child undernutrition can have significant developmental and
socioeconomic costs exacerbating long-term development challenges. For Rwanda, the total estimated
annual losses associated with undernutrition are estimated at US$820 million, equivalent to 11.5 percent of
GDP in 2012. In Ethiopia, child mortality associated with undernutrition has reduced its workforce by 8
percent. Prevailing dry conditions across the Horn of Africa in 2019, for example, led to sharply increased
food prices, reduced water availability, and crop and livestock losses, all with implications for food security
and human health. Somalia, the most drought-prone country in the region, has faced both chronic food
insecurity and high levels of malnutrition since the 1970s; as a result of the 2008–2010 drought, for example,
the country experienced a famine during which one-third of children in southern Somalia were malnourished.

INFRASTRUCTURE AND ENERGY
More frequent and intense heavy rainfall
events are likely to increase the impact of
floods and landslides on infrastructure and
associated energy, water, and transportation
services across East Africa. From March
through August 2018, heavy rainfall across
much of the region led to damage and
destruction of critical infrastructure, including
more than 100,000 houses as well as bridges,
roads, dams, power lines, schools,
health facilities, latrines, and markets.
Hydropower provides a substantial portion of
the region’s power generation and has been
affected heavily by drought events in recent
years; projections of reduced river flow
in the Nile Basin may exacerbate this trend.
Heavy rainfall and subsequent soil erosion
are further expected to increase siltation of
reservoirs critical for hydropower production.
In Kenya, hydropower production is reduced
by up to 40 percent in drought years, leading
to persistent power outages and reliance on
more expensive petroleum-based thermal generation. Research shows that, if constructed, hydropower
dams planned for East Africa before 2030 could put 70 percent of the region’s electricity supply at risk from
climate variability and change, as they rely on areas with similar rainfall patterns. Although most precipitation
models project an overall increase in annual precipitation regionally, interannual erratic rainfall variability
increases the risk of drought regionally. As a result, the increased frequency of drought could greatly reduce
the water impounded in reservoirs supplying hydropower dams. (12, 26, 27, 29, 31, 43, 52, 57, 58, 59, 60, 61,
62)
Along the coast, more than 40 million people are expected to live no more than 10 m above sea level by the
2060s, where sea level rise and coastal erosion will increasingly threaten infrastructure through damage and
inundation. In Dar-es-Salaam alone, infrastructure assets of US$5.3 billion and the country’s main port are
increasingly at risk from coastal flooding. Mombasa and its port, Kilindini, are also sensitive to sea level rise,
and models estimate assets of up to US$4.8 billion will be exposed to flooding and inundation from sea level
rise by 2050. (26, 40, 49)
ECOSYSTEMS
While complex interactions among drivers of ecosystem structure, composition, and function make climate
impacts difficult to predict, rising temperatures and shifting rainfall patterns are expected to further stress
East Africa’s rich biodiversity, which already faces pressure from human activities (e.g., deforestation,
pollution, wildlife trafficking and poaching, expanding settlements, conversion to agriculture). Increasing
heavy rainfall events and more intense droughts are expected to intensify land degradation and reduce
vegetative cover across many of the region’s diverse ecosystems that provide critical products and
ecosystem services, including forestry, fishery, pastoral and tourism-based livelihoods, as well as critical fuel
and food supplies and water regulation (e.g., filtration, groundwater recharge). Rising temperatures, storms,

and floods also pose increased threats to ecosystems through direct damage, shifted distributions of native
and invasive species, increased physiological stress, disrupted predator–prey relationships, and increased
wildfire risk. For example, an estimated 107 mammal, 199 bird, 31 fish, 34 amphibian, and 79 plant species
in the Albertine Rift region (covering parts of Burundi, DRC, Rwanda, Tanzania, and Uganda) are highly
vulnerable to climate change due to thermal sensitivity and/or projected changes in habitat suitability.
Warming of the region’s freshwater lakes, important for livelihoods and protein, has already led to decreased
nutrient cycling and reduced fishery productivity in Lakes Victoria, Tanganyika, Kivu, Malawi, and others. (9,
32, 39, 52, 54, 69)
Meanwhile, shifts in agroecological zones may
lead to agricultural expansion into previously
intact forests and grasslands, particularly in
highland areas. Shifting ecological zones may
also change the suitable ranges of plant and
wildlife species, themselves adversely impacting
the endemic freshwater fish, hippos, and the
endangered African wild dog, that depend on
these species. Along the region’s coastline, sea
level rise, warming ocean temperatures, and
ocean acidification are increasing coastal
erosion and threatening mangrove habitat, coral
reefs, coastal biodiversity, and fishery
productivity. Ocean warming is expected to
decrease the region’s marine biodiversity and
fishery catch potential by three or more times
the global average by 2100. This has impacts
on artisanal and industrial fisheries that also
face increasing pressure from offshore fishing
by foreign commercial vessels. In Tanzania, for
example, fisheries provide more than 4 million jobs and an important protein source in coastal and inland
regions; increasing ocean temperatures and sedimentation from heavy rains further threatens fisheries, with
consequences for livelihoods and nutrition nationwide. Mangroves and coral reefs are critical for fisheries,
storm surge protection, and the tourism economy. The region’s coral reefs are highly susceptible to heat
stress and have not yet fully recovered from the 1998 coral bleaching event. (5, 10, 16, 39, 52, 54, 64, 73)
POLICY CONTEXT
INSTITUTIONAL FRAMEWORK Regional cooperation is mainly coordinated through the Common Market for Eastern and Southern Africa
(COMESA) and East African Community (EAC). Both institutions cooperate on climate change initiatives
along with the Southern African Development Community (SADC). COMESA and EAC have both
implemented climate change programming supported by a range of bilateral and multilateral donors,
including the five-year Tripartite COMESA–EAC–SADC Climate Change Program which increased
investments in climate-resilient and carbon-efficient agriculture. COMESA, a free trade area among 21
member states, engages member government ministries, parliamentarians, and civil society organizations to
encourage participation in climate change adaptation and mitigation. COMESA aims to mainstream climate
change throughout its work, and it houses a Climate Change Unit.

The EAC, an intergovernmental organization of six partner states, encourages regional integration among its
members and aims to address climate change impacts. The EAC stated that it intends to reopen its Climate
Unit, which closed in 2016 due to a lack of funds. The Lake Victoria Basin Commission (LVBC) of the EAC
coordinates sustainable development and management of the Lake Victoria Basin. Additionally, in 2013, the
United Nations Framework Convention on Climate Change (UNFCCC) and the East African Development
Bank (EADB) signed a partnership agreement to establish a Regional Collaboration Centre (RCC) in
Kampala, Uganda, to support national climate action and investments in sustainable development. The RCC
fosters collaboration between Djibouti, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania, Uganda
and 16 other African countries on adaptation and mitigation actions, and since 2015, has been tasked with
supporting the implementation of countries’ Nationally Determined Contributions (NDCs).
REGIONAL POLICIES AND STRATEGIES • The COMESA Medium Term Strategic Plan (2016-2020) includes initiatives to mainstream climate
risk analysis and resilience-building into COMESA-wide operations and specifically references
climate-smart agriculture, environmental safeguards for climate risk, and early warning systems.
• The 5th EAC Development Strategy (2017-2021) recognizes regional climate-related risks, and the
strategic objectives include enhancing regional mechanisms and strategies for climate change
management.
• The EAC Vision 2050 (2016) aims to expand climate services, operationalize the EAC Climate Fund,
and enhance climate change adaptation and mitigation among partner states.
• The EAC Climate Change Policy (2011) outlines the preparation and implementation of collective
measures to address climate change in the region for partner states and other stakeholders.
• The EAC Climate Change Strategy (2011) guides the implementation of the EAC Climate Change
Policy.
• The EAC Climate Change Master Plan (2011-2031) provides a long-term vision and basis for partner
states to adapt to and mitigate climate change.
• The Lake Victoria Basin Climate Change Adaptation Strategy and Action Plan (2018-2023) presents
a comprehensive roadmap for addressing and adapting to climate change impacts.
SECTOR-SPECIFIC INTEGRATED PLANS A number of the EAC’s sectoral strategies also support regional adaptive capacity. These include the One
Health Regional Risk and Crisis Communication Strategy (2018-2023), Strategy to Combat Poaching, Illegal
Trade and Trafficking of Wildlife and Wildlife Products (2017-2022), and Food Security Action Plan (2011-
2015: a more recent version was not found). COMESA also houses relevant programs on regional livestock
and fisheries. EAC and COMESA have both adopted the Comprehensive Africa Agriculture Development
Program (CAADP) Regional Agriculture Investment Plan that aims to boost food security and agricultural
productivity.
NATIONAL STRATEGIES AND PLANS In addition to regional strategies, all countries in the region are addressing climate change at a national level
(see table below). Each country has submitted at least two National Communications to the UNFCCC,
except for South Sudan, which submitted its first National Communication in August 2019. As of August 2019,
three countries (Ethiopia, Kenya, and Sudan) have submitted National Adaptation Plans (NAPs), and others
are either a) in various stages of development, submission, and approval of Readiness and Preparatory
Support proposals to the Global Climate Fund for NAP development, or b) have received support from the
National Adaptation Plan Global Support Programme. Most countries also have dedicated climate change
policies or have integrated climate change into national development or environment plans or legislation. In
the case of Sudan, an aim of the country’s National Adaptation Plan is to promote climate change integration
into policy, which will likely be reflected in the country’s forthcoming Five Year Economic Reform Program
CLIMATE RISK PROFILE: EAST AFRICA | 10
(2020-2024). Additionally, some countries have integrated climate change into sectoral strategies, such as
Uganda’s Agriculture Sector Strategic Plan (2015-2020), Kenya’s Draft Livestock Policy (2019), and
Rwanda’s National Policy for Water Resources Management (2011).
